You can make a nice text editor, maybe a photo or media viewer. If anti-piracy measures are in play, emulators probably won't be possible. Emulators will be possible, I'm just exaggerating.
Hacking? Modding? Ha, that's a nice joke.
Developing a kernel exploit will allow us to define the userland sandbox as opposed to inheriting it from the browser we hook into. Dumping the keys in OTP will allow us to decrypt the system to support newer firmware versions FASTER. Emulators will be possible. We will enable you to load your own applications, but we're not going out of our way to let you load Nintendo's official applications as that will just lead to mass piracy.
This seriously sucks! I was looking forward to this exploit
If I want to backup my Wii U games, so be it. If I want to play retro games that I legally dumped with Retrode, so be it. You're going down a slippery slope that will turn you into control freaks. Sorry, but now I'm rooting for those awful, nasty,freedom loving pirates you hate so much.
Well then code it yourself or if you're too much of a skrid go buy an ODE in a couple of months. No respected developer is going to build you a free warez loader. When we develop a framework for homebrew and gamemodding we expect to get something back from the community by having them create cool things. You understand that right?
A warez loader provides NOTHING for us or the community other than enabling leaching skrids to pirate and painting a big red target on our backs to Nintendo.
